标题: 求助各位大神！！！【急】
程序如下：
  1. model:
  2. sets:
  3. jing/1..8/:a,b;
  4. nian/1..5/:z;
  5. jl/1..3/:L;
  6. link1(jing,nian):x;
  7. endsets
  8. data:
  9. a=25,36,32,15,31,28,22,12;
  10. b=5,7,5,4,6,5,5,3;
  11. enddata
  12. min=z(1)+z(2)+z(3)+z(4)+z(5);
  13. z(1)=0.66*(Q^0.51)*L(1)+@sum(jing(i):b(i)*x(i,1));
  14. z(2)=0.66*(Q^0.51)*L(2)+@sum(jing(i):b(i)*@abs(x(i,1)-1)*x(i,2));
  15. z(3)=0.66*(Q^0.51)*L(3)+@sum(jing(i):b(i)*@abs(x(i,1)-1)*@abs(x(i,2)-1)*x(i,3));
  16. z(4)=@sum(jing(i):b(i)*@abs(x(i,1)-1)*@abs(x(i,2)-1)*@abs(x(i,3)-1)*x(i,4));
  17. z(5)=@sum(jing(i):b(i)*@abs(x(i,1)-1)*@abs(x(i,2)-1)*@abs(x(i,3)-1)*@abs(x(i,4)-1)*x(i,5));
  18. z(1)<=60;z(2)<=60;z(3)<=60;z(4)<=60;z(5)<=60;
  19. @sum(jing(j):a(j)*x(j,1))>=106.4961;
  20. @sum(jing(j):a(j)*@abs(x(j,1)-1)*x(j,2))+@sum(jing(j):0.9*a(j)*x(j,1))>=128.1795;
  21. @sum(jing(j):a(j)*@abs(x(j,1)-1)*@abs(x(j,2)-1)*x(j,3))+@sum(jing(j):(0.9^2)*a(j)*x(j,1))+@sum(jing(j):0.9*a(j)*x(j,2))>=145.9933;
  22. @sum(jing(j):a(j)*@abs(x(j,1)-1)*@abs(x(j,2)-1)*@abs(x(j,3)-1)*x(j,4))+Q+@sum(jing(j):(0.9^3)*x(j,1))+@sum(jing(j):(0.9^2)*x(j,2))+@sum(jing(j):0.9*x(j,3))>=159.3173;
  23. @sum(jing(j):a(j)*@abs(x(j,1)-1)*@abs(x(j,2)-1)*@abs(x(j,3)-1)*@abs(x(j,4)-1)*x(j,5))+Q+@sum(jing(j):(0.9^4)*x(j,1))+@sum(jing(j):(0.9^3)*x(j,2))+@sum(jing(j):(0.9^2)*x(j,3))+@sum(jing(j):0.9*x(j,4))>=172.6623;
  24. L(1)+L(2)+L(3)=20;
  25. Q>=100;
  26. @for(link1:@bin(x));
  27. end

执行后显示：
error code:81
error text: no frasible solution found.

请大神们一定要帮帮小弟啊！！！
